The growth is good, but seems stunted, i have noted that the new leaves are growing in slowly. If you agree that i am lacking phosphorus let me know what chemical nutrient i should add. I am using cal-mag plus and pure grow, but neither contain phosphorus. If you disagree with my analysis let me know what you think. Thanks

your stems ARE REDISH BECOUSE YOUR THE TEMPERATURE IS TOO LOW...!!!!!

your temp is ~ 19 'C, by the look of the plants on the photos...

- make it 24'C... red will go away...

...peace...
